Questions of this type are answered in the Ada Reference manual.
This particular case is covered in B.3 (68), viz.:
An Ada access T parameter, or an Ada out or in out parameter of an
elementary type T, is passed as a t* argument to a C function, where t is
the C type corresponding to the Ada type T. In the case of an elementary out
or in out parameter, a pointer to a temporary copy is used to preserve
by-copy semantics.
